welcome to Apocalypse Audio, your haven for DIY guitar effects in the end times. so, start prayin to the fuzz gods, savin up those parts, and remember, when the big one goes off- keep your transistors shielded from those pesky electromagnetic pulses!

GREEN BOMB FUZZ

here's something i was working on the other night.  it's a revved up mosrite fuzzrite based off of gus's gusrite circuit.  i basically juiced up the gain even more, did some stabilization and frequency response adjustments and added a nfb based tone control to add even more weird phase shaping possibilities than what was had in the original.  it's basically like a fuzzrite on steroids.  i'd suggest a mid gain transistor for Q1 and a high gain for Q2.  different transistors do different things, so it's worth trying out some different ones.  oh, and it can totally do that spirit in the sky thing perfect!  when you turn the gain all the way up you get that ratty almost misbiased thing that greenbaum had going on in his onboard fuzz.  back the gain off and rattyness goes away.  this thing is my new go to for crazy psych madness.  if you want more of a honky sound, lower the transistor gain a bit.  i'll probably try and do some more tweaks in the future, and i'll post them when i get a chance.

also-  i've got a tagboard layout that i'll post when i get it verified. ;]

here are the schematics from Gus's rite fuzz and the mosrite Fuzzrite for reference.  if the owners have a problem with my posting them here, i will gladly take them down.



also, i was asked on FSB to describe the added tone control.  i tried to explain it to the best of my ability.  if anyone has anything to add, please, feel free.


the fuzz control on the fuzzrite works by adding the output of the first stage, an out of phase signal, with the output of the second stage, in phase signal.  this is what produces some of the thin, hollowed out, phase cancelled sounds that the fuzzrite is known for.  the shape control takes the non-inverted output of the first stage, with the output of the second stage, which also gets mixed in with the output of the first stage with the fuzz control.  the shape control has a low pass filter due to the .01 cap to ground, so when when it's negative feedback takes place, it only cancels out the lower frequencies and leaves the highs.  with this control you are still able to get the brite, zippy sounds of the original fuzzrite, but are now also able to get the thicker sounds of gus's ritefuzz- all through the same negative feedback techniques similar to what was used in the original fuzzrite!
